Teaspoons to Milliliters

Guide to Converting Teaspoons to Milliliters (mL)

Converting teaspoons (tsp) to milliliters (mL) is a critical daily calculation in liquid medication dosing, culinary baking, coffee brewing, and mixology. In pharmaceutical dosing, accurately translating liquid medication volumes between imperial teaspoons and metric milliliters is vital to prevent under- or over-dosing.

Understanding US Customary vs Metric Teaspoons

Teaspoon standards vary slightly depending on whether you are measuring in a culinary or medical context:

• US Customary Teaspoon: Standard in US baking recipes. 1 US tsp = 4.92892159375 mL (approx. 4.93 mL).
• Metric Teaspoon: Standard in international medical dosing and metric cooking (UK, Australia, Canada). Defined as exactly 5.00 mL.
• US Food Labeling Teaspoon: Defined by US FDA regulation for nutrition panels as exactly 5.00 mL.
• Conversion Formula (US Customary): mL = Teaspoons × 4.92892.

Liquid Medication Dosing & Culinary Safety

Medical professionals strongly advise using calibrated metric dosing syringes (5 mL) rather than household silverware teaspoons when administering liquid pediatric medicine, as kitchen spoons vary widely in actual volume (3 mL to 7 mL).
